TURPENTINE-HACK.

Specification of Letters Patent.

Patented Aug. 25, 191 1.

Application filed December 8, 1913. Serial No. 805,343.

To all whom it may concern I Be it known that I, J osnrrr T. VVonoEsrER,

a citizen of the United States, residing at Mobile, in the county of Mobile and State of Alabama, have invented certain new and useful Improvements in Turpentine-Hacks; and I do hereby declare the following to be a full, clear, and exact description of the 1nvention, such as will enable others skllled in the art to which it appertains to make and use the same.

The present invention relates to implements employed for hacking pine trees and removing the crude turpentine gum therefrom after it has exuded from the cuts, and has for its purpose to provide a tool of that character in which the blade-carrying member is secured to the handle in a manner to effectively withstand heavy wear; wherein the working blade may be readily adjusted to project more or less from the handle to efiect the cut desired; and one wherein a number of different tools are interchange-- able with the same handle, and may be replaced at will.

With the present used tools of this character, the instrument is attached to the handle by iron rings that are driven on so hard, to secure the desired hold, that there is considerable loss in time to remove the instrument for replacement or adjustment, and in the turpentine industry this loss is greater than the cost of making new handles and securing rings. To obviate these disadvantages the present invention proposes to produce an implement wherein the Working blades may be readily interchanged or adjusted.

With these and other objects in view the invention consists in the novel details of construction and combinations of parts more fully hereinafter disclosed and particularly pointed out in the claim.

In the accompanying drawings forming 46 a part of this application, and in which similar reference symbols indicate corresponding parts in the several views: Figure 1 is a side elevational view showing a turpentine hack secured to the handle. Fig. 2

is a top plan View of the same, and Fig. 3

is an enlarged detail view of the clamping sleeve.

Referring to the construction in further detail, the implement consists of a handle 1,

of any suitable material and design, having fitted thereon a metal sleeve 2, that is split or divided lengthwise, as at 3. At its upper end the sleeve 2 is constructed with a pair of integral and offstanding parallel lugs 4, having registering apertures 5, and at its lower end a pair of offstanding and diagonally disposed lugs 6 having registering slots 7. The two pairs of lugs are located adjacent the divided portion of the sleeve, and have for their purpose to provide means for holding the hack or other tool, and have fastening members for their own securement on the handle.

A hack 8 is constructed after the usual manner, and has its stock or shank 9 fitting between the upper and lower pairs of lugs of the sleeve. A. pin or bolt 10 passes through the apertures 5 of the lugs 4E and a similar aperture in the shank 9, and provides a fulcrum for the shank of the hack. A second bolt or pin 11 passes through the slots 7 of the lower lugs and an opening in the shank 9, and allows of free movement of the shank for adjustment, and provides the lower securing means for the shank when the hack has been set to the desired position. The bolts or pins 10 and 11 have ordinary heads 1O and threaded nuts 11*, as shown in Fig. 2. The pin 11 is of smaller diameter than the width of the slots 7 in order to allow for the angular adjustment of the shank 9, since said pin 11 moves in the arc of a circle by such adjustment. The cutting edges 12 and 13 of the hack (see Fig. 1) are concave, to the end that the instrument will better serve the cutting shade streaks on'the tree. The handle 1, together with the clamping sleeve 2, serve for bolding the hack, as shown in Fig. 1, or the other design, andin each instance the instrument so held may be readily adjusted, as indicated by the broken lines in Fig. 1.

It is obvious that those skilled in the art may vary the details of construction and arrangement of parts without departing from the spirit of my invention, and therefore I do not wish to be limited to such features except as may be required by the claim.

I claim In a tool of the character described, the combination of a handle; a split sleeve fitting on the handle and having an upper and a lower pair of integral lugs, said upper lugs provided with apertures and said lower lugs disposed diagonally relative to the axis of the sleeve and provided with diagonal slots; a Working member having a shank fitfor securing the split sleeve to the l1anclle5 ting between said upper and lower pairs of substantially as. described. 10'

lugs; a bolt passing through said upper lugs In testimony whereof, affix my signaand said shank and providlng a pivotal bear- I ture in presence of two Witnesses.
